Todays Computers Have Computer Memory SDRAMToday we have a lot of expectations of our computer. They need to work faster and that is why the market requires more from computer memory. Sometimes it can be difficult to understand about different types of computer memory. It is important to note though that most modern day computers run on computer memory SDRAM of one form or another. Here we will go over the different types of memory that have existed and how they worked SIMM memory is Single In Line Memory Modues. These were used in computers during the 80s. Most 286s and 386 computers had some form of SIMM memory. SIMM memory stores a single row of DRAM, EDO or BEDO chips. DIMM Memory- These are Dual In Line Memory and are used in the lower Pentium computers. They can usually be found in the Pentium I, II, and sometimes III. DIMM memory modules installed somewhat differently from the SIMM memory modules. They installed straight up on the Mother board. Later DRAM memory came out. This is actually called Dynamic Random Access Memory and is what most computers use today. This type of storage started being measured in Megabytes instead of bytes, like 64Megabytes, or 128 megabytes. In 1996, what we now know as computer memory SDRAM finally arrived. The actual real name for computer memory SDRAM is synchronous dynamic random access memory and what made this different from ram memory is that it has can perform actions in sync with the CPU and Motherboard bus. And all of this in laymens terms means that it is easier to perform several actions at once. It allows the CPU to receive a command before having finished the previous command. There is a delay and that delay is called latency, but the higher the capacity of the SDRAM module the smaller the latency will be. Computer memory SDRAM works off of a clock pulse. That is why the SDRAM modules are rated according to their clock rate and their read cycle time. The time it takes the cpu to read the cycle time of the SDRAM Module affects the delay between making a command and the computer actually executing it. That is why the higher the SDRAM MB that you have in the computer the faster your computer will perform an application and the less latency it will have. Synchronous DRAM or Computer memory SDRAM has been around since the early 70s but it wasn't until the early 90s that it began to be used universally by the computer industry. Samsung introduced the first Synchronous DRAM module in 1993 and by 2000 Computer memory SDRAM had replaced all other types of DRAM computer memory, because it was much faster than the others. All SDRAM up until 2007 was manufactured and met the JEDEC standards. This is an electronic industry association that helps correlate the interoperability of electronic components. Today new pc units are not being sold with the new PC systems. Most new PC systems now have DDR2 SDRAM memory and some even have DDR3, but these are more expensive than the new DDR2 products. |
